The survey/results are not in an appendix

Since you can’t refer to an appendix, you should instead refer to a “personal communication”. Using this term indicates that the survey/results are not available to third parties – including the reader.

We recommend that you always include your survey and its results in an appendix. If that isn’t possible for some reason, you can avoid having to use “personal communication” by going for the Intranet solution.
